Alla ricerca dei fattori rilevanti nell’adozione dei sistemi di gestione della performance nelle amministrazioni pubbliche territoriali. L’analisi di…
2013
La ricerca scientifica ha dimostrato che la gestione della performance nelle amministrazioni pubbliche sta oggi spostando il proprio focus dalla mera attività di raccolta e rendicontazione di dati alla generazione di informazioni atte a supportare la formulazione di decisioni. L’analisi comparativa dei casi di studio analizzati in questo articolo mira ad identificare i fattori critici sottostanti alla progettazione e all’utilizzo dei sistemi di gestione della performance nelle amministrazioni regionali. Da questa analisi emerge che alcune variabili risultano essenziali ai fini di un’efficace adozione dei sistemi di performance management. Tra queste variabili sono annoverabili: il ruolo del…
A Survey on Daylighting Education in Italian Universities : Knowledge of Standards, Metrics and Simulation Tools
2021
Daylighting is a strategic topic to achieve sustainable buildings, so it is more and more imperative that it is implemented in architecture curricula to prepare a new generation of daylighting-oriented practitioners. In this frame, the DAYKE project (Daylight Knowledge in Europe) was set up to explore the level of knowledge about daylighting among European professionals and students. DAYKE-Europe was replicated as DAYKE-Italy to study the knowledge of daylight standards, metrics and software among Italian architecture students, and to compare it to that observed within DAYKE-Europe. A sample of 542 questionnaires were collected in five universities. Primary outcomes were: (i) a general low …

2017
Kvalifikācijas darba „Web informatīvā sistēma” mērķis ir izveidot īpašumu sludinājumu publisku tīmekļa vietni, kas aizstās esošu „ArtEstate” kataloga sistēmu. Šī programmatūra nodrošinās iespēju klientiem atrast un saglabāt īpašumus pēc izvēlētajiem kritērijiem, kā arī sazināties ar uzņēmuma darbiniekiem jaunu sludinājumu pieteikšanai un konsultācijām. Darbiniekiem tiks paredzēta vienkārši lietojama sludinājumu un mājas lapas pārvaldes sistēma ar vairāku vienlaicīgu lietotāju pieslēgšanās iespēju. Izstrādes procesā tiks iegūta uzņēmumam būtiska programmatūra, kas klientiem atvieglos nekustamo īpašumu komerciālās darbības.
An active form of sphingosine kinase-1 is released in the extracellular medium as component of membrane vesicles shed by two human tumor cell line.
2010
Expression of sphingosine kinase-1 (SphK-1) correlates with a poor survival rate of tumor patients. This effect is probably due to the ability of SphK-1 to be released into the extracellular medium where it catalyzes the biosynthesis of sphingosine-1-phosphate (S1P), a signaling molecule endowed with profound proangiogenic effects. SphK-1 is a leaderless protein which is secreted by an unconventional mechanism. In this paper, we will show that in human hepatocarcinoma Sk-Hep1 cells, extracellular signaling is followed by targeting the enzyme to the cell surface and parallels targeting of FGF-2 to the budding vesicles. We will also show that SphK-1 is present in a catalitycally active form i…
Clostridium difficile Toxins Disrupt Epithelial Barrier Function by Altering Membrane Microdomain Localization of Tight Junction Proteins
2001
ABSTRACT The anaerobic bacterium Clostridium difficile is the etiologic agent of pseudomembranous colitis. C. difficile toxins TcdA and TcdB are UDP-glucosyltransferases that monoglucosylate and thereby inactivate the Rho family of GTPases (W. P. Ciesla, Jr., and D. A. Bobak, J. Biol. Chem. 273:16021–16026, 1998). We utilized purified reference toxins of C. difficile , TcdA-10463 (TcdA) and TcdB-10463 (TcdB), and a model intestinal epithelial cell line to characterize their influence on tight-junction (TJ) organization and hence to analyze the mechanisms by which they contribute to the enhanced paracellular permeability and disease pathophysiology of pseudomembranous colitis. The increase i…
Impact of Legislative Changes on the Availability of Medicines and Pharmacovigilance Activities
2021
Zāļu pieejamība ir vispārējas cilvēktiesības, tomēr tā joprojām saglabājas globāla problēma. Šajā pētījumā par objektu izvēlēts Latvijas lielākās kaimiņvalsts – Krievijas Federācijas (KF) – zāļu normatīvais regulējums, kurā 2010. gadā notika radikālas izmaiņas, kas noveda pie papildu administratīvā sloga un ietekmes uz zāļu pieejamību un farmakovigilances aktivitātēm. Tā kā Latvijas farmaceitiskajiem uzņēmumiem un citu Eiropas Savienības (ES) valstu zāļu ražotājiem KF tirgus ir nozīmīgs, tiem būtu noderīgi iegūt zinātnisku ieskatu zāļu reģistrāciju regulējošos procesos kas palīdzētu uzlabot to darbību. Pētījums ir nozīmīgs arī valsts iestāžu darbiniekiem, lai paredzētu sekas un plānotu norm…
PSA and PSA Kinetics Thresholds for the Presence of 68Ga-PSMA-11 PET/CT-Detectable Lesions in Patients with Biochemical Recurrent Prostate Cancer
2020
68Ga-PSMA-11 positron-emission tomography/computed tomography (PET/CT) is commonly used for restaging recurrent prostate cancer (PC) in European clinical practice. The goal of this study is to determine the optimum time for performing these PET/CT scans in a large cohort of patients by identifying the prostate-specific-antigen (PSA) and PSA kinetics thresholds for detecting and localizing recurrent PC. This retrospective analysis includes 581 patients with biochemical recurrence (BC) by definition. The performance of 68Ga-PSMA-11 PET/CT in relation to the PSA value at the scan time as well as PSA kinetics was assessed by the receiver-operating-characteristic-curve (ROC) generated by plottin…
Meprin β: A novel regulator of blood–brain barrier integrity
2020
The metalloprotease meprin β (Mep1b) is capable of cleaving cell-adhesion molecules in different tissues (e.g. skin, kidney and intestine) and is dysregulated in several diseases associated with barrier breakdown (Alzheimer´s disease, kidney disruption, inflammatory bowel disease). In this study, we demonstrate that Mep1b is a novel regulator of tight junction (TJ) composition and blood–brain barrier (BBB) integrity in brain endothelium. In Mep1b-transfected mouse brain endothelial cells (bEnd.3), we observed a reduction of the TJ protein claudin-5, decreased transendothelial electrical resistance (TEER) and an elevated permeability to paracellular diffusion marker [14C]-inulin. Analysis o…
